MG MGB Technical - HS6 1.75' Inlet Manifold

Hi guys,

I bought a pair of HS6 carbs and matched manifold of a guy a few years ago, and I've just got to fitting them (they fit perfectly well).

I was after a stainless steel heatshield for them, and spoke to a guy who makes them..........

His design is for the top two inner studs on the manifold with a distance between their centres of 132mm.

My manifold has the measurement at 150mm. My manifold has the part number 12H2748, but I can't find that in existance anywhere (Moss, MGOC, Burlen, Brown and Gammons).

Can anyone out there in "MGLand" tell me:
a) what measurement between the centres of the top two inner studs are on their HS6 manifold?
b) if they know of a site that refernces 12H2748 or what that part was used for in the dim and distant past?

Cheers guys, you haven't failed me yet.

Many thanks,

Grant :-)

Grant,
I bought my heatshields from MGOC I think - they're separate, one for each side. I can measure the manifold if you like but it came direct from Burlen so may not be the same as yours.

Grant, the manifold may be 1800 Land Crab, or Marina. I think they were the only production Leyland cars with H6 or HS6

Hi guys,

thanks fo the feedback.

I had a look on the Burlen site last night and checked the carb numbers, and they are indeed from a land crab - well spotted Colin!

Does abnyone have any details/thoughts on the performance of this manifold vs. a newer one from MGOC or Burlen,e.g will the separation of the carbs make a difference?

Neil, if you could measure the manufoild, that'd be great, just so I can compare it to a proven "MGB" manifold source :-)

Many thanks,

Grant :-)

Ste, sorry I meant on a B series engine. Of course there were many other cars with 1 3/4 SU, including TR4 etc.

It was the manifold that we were talking about

G Hudson- Have a look at the HIF Needle thread current on this board,I outline the spot on technique for accurate needle selection for your carbs. It is so good, it will literally write the new book on tune tech for our cars. Cherios, Vic
